pytest-test-data-factories

Test data factories eliminate duplication and make tests more maintainable. Instead of recreating Order objects with the same fields in every test, factories provide sensible defaults and allow customization only where needed.

Patterns for creating reusable test data: factory functions for domain objects, builder patterns for complex objects, fixture factories, parameterized test data, test data inheritance, and type-safe test data generators. Use when creating test data repeatedly, building objects with many optional fields, or generating realistic test datasets. Use when: Writing tests that need domain objects, creating fixtures for multiple tests, generating test data with defaults, building complex objects with optional fields, or parameterizing tests with various data.
